Fig. 5 is an riveted tot e. asmdicated at29mF1g E i I enlarged detail l'mgnwnho-y plan "iew show- 1.- The construction and arrangementoitha 119 65- seen that t parts are such that the disk 26, which is provided with a knurled periphery or edge 30, is adapted to receive a rotative adjustment on the caring screws 25 around the. axis of the platen and to turn with the platen by reason of the dish spring 27 interposed between the disk 26 and the right-hand platen head except when arrested as will hereinafter more clearly appear when the platen may turn independently ot' the disk. Situated at the outer side of the disk 26 is a second disk or carrier 31 provided with an indicatorv which, in the resent instance, is in the nature of a v lateral y projecting pin 32 riveted to the disk as indicated at 33 at Fig. l. The indicating pin 32 is situated at the same distance from the axis of the platenIas the stop pin 28 although it is out of the path of said stop pin. A bearing sleeve 34 for the platen shaft is received in an opening in the end plate 10 of the platen frame or carriage and is secured against movement in said operung by a setv screw which extends through a threaded opening in the end plate 10 and bears at its inner end against the sleeve 84. This bean ing sleeve is provided at its inner end with an enlarged cylindrical member 36 which, in the Monarch machine, constitutes a ball bearing thrust box for the platen. The periphery of this box in the present instance constitutes a bearing for a hub-like portion 37 which pro jects from the disk 31 so that the disk 31 is adapted to turn around the axis of the platen on the member 36. From an ins ection of Fig. 4 itwill be seen that a curved. eaf spring is riveted ht one end'as at 39 to the hub 37, whereas the opposite or free end of the spring carries a friction device or pin 40 riveted thereto at 41.- This friction in 40 passes through an opening 42 in the ub 37 and the inner conoidal end 43 of the pin is reccived in a circumferential or peripheral groove 44 in the periphery of the member 36-, said groove being V-shaped in cross section.

By this arrangement the disk 3] is preven ed from accidental displacement longitudinally or" the platen from the bearing member 36 on which the hub 37 is mounted. At the same time the pressure of the spring 38 on the pin produces a l'rictioual contact between the pin and the member 36 so as to retain the disk 31 in any position to which it may be rotatively adjusted around the axis of the platen.

A fixed stop 45 is secured to the right-hand end plate or bar 10 of the platen frame or carriage by ascrew 46. This fixed stop is in the nature of an angle iron or bracket, one end or foot portion 47 of which is secured by the screw 46 to the carriage. A ortion 48 of the stop extends longitudina ly of the platen and is bent upwardly and forwardly at 49 to provide a stop member or portion which cooperates with the rotary stop From an inspection of Figs. l and 2 it will be 0 portion 48 of the fixed stop extends outside "of the peripheries of the two drsks 26 and 3t but at the upwardly and forv wardly extending end or arresting portion 49 of the stop extends into the path of the on its periphery or ,edge'as indicated at 50 may be turned around the axis of the platen to bring the indicator or laterally projecting pin 32 to any desired position am that the disk will be retained in its adjusted position by the frictional connection between said disk and the platen frame or carriage. It will'also be seen that the stop carrying disk 26 will be rotated v:ith the platen through the frictional connection between the platen and said disk until the stop 28 is brought into contact with the fixed stop 45 when the stop and disk 26 will be arrested and a. further rotation of the laten may be effected after the stop has een arrested. It will likewise be seen that during the rotation of the stop 28 in one direction it is brought into registration with the indicating pin 32, that is to say, there is a time during the rotation of the stop in 28 with the platen when said in will be indicating pin 32;

For.condensefl record work it is necessax-y 1n the first instance to set the devlces for the particular character of bill or invoice sheets to be employed. In order to do this the platen is first rotated forwardly or in the direction of the arrow in Fig. 2 until the rotary 'sto 28 which rotates therewith is in contact with the fixed stop 4511s shown in said figure. A bill or invoice sheet of the character to be employed is then introduced into the machinepnd a further forward rotation'of'theplater) is effected until the int on the bill sheet where the first line ot writing is to appear is brought to the printing line indicated by thedotted line a. It may be assumed, by'way of example, that the forward rotation of the platen just described corresponds to twenty-six teeth of the line spacing wheel. ment of the platen the rotary stop 28 remains in engagement with the fixed stop 45 and the platen turns independently of. the rotary v stop. 'A rearward rotation of the platen or a rotation thereof in the directionopposite to that indicated by the arrow in F1gQ2-is now effected until the leading edge of the bill sheet is at the oint where it was introduced into the mac e or in other words isv in the bight between the main feed rollers 51 and the platen.

The extent of 'bsokward notation to be given the platen may be accurately deter-v minedby c rbught into alinernent with the During this forward move- 1 the platen forward a tooth is of the line spacing; wheel at a time until the proper point on t is bill has been brought to the printing line, the operator counting the number of chairs or teeth. -It has been assumed that this movement corres onds to the distance of twenty-six teeth 0 the line sparing wheel in the resent example. -It follons therefore that iPitrc-quired a forward rotation of the platen for a distance of y from the position shown in Fig. 2 around to a posiliml mriesponding substantially to the phsi'iui of the stop 32 in said figure. The

disk n is then adjusted around the axis of the pla en until the indicating pin 32 is in alincmcnt or register with the stop pin 28. The bill sheet is hen removed'and a forward rotation is imparted to the platen to carry the sicp pin 28 sway from or out of re ister with the pin 32 and into contact wit i'the fixed stop 45. The devices are now set and a further setting of the parts is unnecessary until the style of hill heads ischanged, that is to say until bill sheets with a larger or smaller printed heading are employed. After the devices have been set in the manner described, and the rotary stop 28 is in ccmtaot with the fixed stop 45, a record sheet, bill sheet. and interposed carbon sheet are intro- (lured into the machine with the leading edges of the sheets to wether or the bill sheet may be given a lean over the record and (urban sheets in the usual manner in order to bring the first line reproduced on the record sheet near the top thereof. The platen is then rotated forwardly until that, port ion of the hill sheet where the first line of writing is to appear, usually the .date line, is brought to the. printing line a. The operator then proceeds to write the bill and a carbon (:1 p lhcrcol' will be reproduced onthc crrrdcnscd record sheet. The operator then line spaces, say a distance c uivalent to three tr-cth of the line spacing w loci, in order to provide a proper s ace between the last line of lhe copy of the ill 'ust reproduced on the record sheet and-the first line of the cop of the next bill to be reproduced thereon. The

' written bill or invoice sheet may now be removed from the machine without-disturbing the platen or the carbon and record sl ie'ets', or the bill shr t may he allowed to remain in the machine. and be fedbsckwardly and for- 19,; V 7 la 'wsrdly with-the record and carbon sheets during the subsequent operations until the bill sheet is fed forwardly to a point where it is I no longer under the control of the paper feeding devices and: may be readily removed from the ma'lpne. During the forward movement 0 ,t m platen descrilml above the stop 28 remains in contact with the fixed sto but. after tlfe bill has been completed am the platen given an additional three line space movement the platen will be turned rear-- wardly at which time the stop 28 will rotate with the platen away from the fixed stop 45. This backward rotation of the platenis cor-- tinued-until the stop 28 is brought into alinement or register with the indicating pin 32. This rearward rotation of he platen is sufficient to c i'cct a,rearward ,iovement of the carbon and record sheets a requisite distance to receive a new bill sheet in its proper rela' tion to the record sheet. The platen isthen given a forward rotation until the stop 28 con tacts with the fixed stop 45 or until the date line on the newly introduced bill is at the printing line. The operator then proceeds' to write the second or newly introduced bill and a co y thereof Will be l'hprmlncorl through t e interposed carbon sheet, the. first line of the copy of the last bill on the record sheet appearing three line space distances from the lastline of the copy of the preceding bill. This operation continues until the condensed record sheet is tilled when a new one may he introduced and the work proceeded with as before. 1 It will be understood that after thedevices are once set a backward and forward rotation and a three line space movement of the platen is all that is required to receive a new bill in proper relation with the record sheet and to properly position the bill sheet to receive the first line of writing and to provide for proper spa'cin between copies of the bills on t e record sheet. The axiom of forward rotation of the platen is determined by observing when the date line on the bill sheet reaches the printing line or when the stop 28 reaches Contact with the fixed stop 45 and the extent of backward rotation of the platen is determined by the re istration of the stop 28 withthe adjustab 0 indicating pin 32.
